Catching Events

Hello All
I am trying to catch a right button down event for a control before the form
sends it to this control; I tried to do that through overriding the WndProc
But it fails!
Is there any way to do that?

What does your WndProc method look like?

const int WM_RBUTTONDOWN = 0x204;
const int WM_RBUTTONUP = 0x205;

protected override void WndProc(ref Message m)
{
switch (m.Msg)
{
case WM_RBUTTONDOWN: MessageBox.Show("Down");
break;
case WM_RBUTTONUP: MessageBox.Show("Up");
break;
default: base.WndProc(ref m);
break;
}
}
